Thailand’s Board of Investment (BOI) grants various incentives to foreign and domestic investors. The main tax incentive in a promotion package is a tax holiday, i.e. exemption from corporate income tax of profits derived by the promoted project. Additional incentives can be granted based on the merits of the project. Dividends distributed from net profits derived by the promoted project during a tax holiday are also tax exempt. Non-tax incentives are also granted, including assistance from government bodies, possibility of land ownership, free repatriation of capital and profits, and less restrictions on employment of foreign workers.
On 15 January 2026, Thailand’s Board of Investment (BOI) introduced various new promotion measures that investors can claim in addition to any existing incentives they receive.
Measure to Maintain and Expand Production Base
BOI Announcement No.1/2569: This measure aims to incentivize large-scale, long-standing investors to continue choosing Thailand as their primary production base. To qualify, an applicant must have been granted investment promotion for at least three projects over the past 15 years, with a combined investment value of at least THB 10 billion (excluding land and working capital). Under this measure, a new expansion project with an investment of at least THB 500 million will receive enhanced incentives depending on its activity group. Projects in groups A1+ and A3, A4 and B will receive an additional 3-year corporate income tax (CIT) exemption, while projects in groups A1 and A2 will receive a 50% CIT reduction for 5 years after their initial exemption period ends. Applications for this measure must be submitted within the 2026 calendar year.
Measure to Promote Comprehensive Business Relocation
BOI Announcement No.2/2569: This measure aims to attract foreign investors to relocate their entire business ecosystem—including manufacturing, regional headquarters, and research and development (R&D) centers—to Thailand. To be eligible, companies must apply for manufacturing promotion concurrently with an International Business Center (IBC) application and must begin operations and generate revenue within three years. Qualifying projects that relocate both manufacturing and an IBC will receive an additional 3-year CIT exemption on their manufacturing income. For projects that relocate manufacturing, an IBC, and an R&D center, the incentive is increased to an additional 5-year CIT exemption, provided the total exemption period does not exceed 8 years. Applications for this comprehensive relocation package must be submitted by the last working day of 2027.
Measure on Stipulation Measure to Recovery the Economy
BOI Announcement No.3/2569: This measure aims to encourage large-scale investors to accelerate actual investment in Thailand. Under this measure, projects in groups A1, A2, A3, and A4 (excluding specific utilities and transport services) that invest at least THB 2 billion—excluding land and working capital—within 12 months of certificate issuance are eligible for additional incentives.
Qualifying companies will receive a 50% CIT reduction for a period of 5 years following the expiration of their initial CIT exemption period. To benefit from this stimulus, applications must be submitted within the 2026 calendar year, and investors must provide proof of actual investment within 18 months of receiving their investment promotion certificate.
